Package name xscreensaver
Date May 2nd, 2007
Advisory ID MDKSA-2007:097
Affected versions CS3.0, 2007.0, 2007.1
Synopsis Updated xscreensaver packages fix vulnerability

Problem Description

A problem with the way xscreensaver verifies user passwords
was discovered by Alex Yamauchi. When a system is using remote
authentication (i.e. LDAP) for logins, a local attacker able to cause
a network outage on the system could cause xscreensaver to crash,
which would unlock the screen.

Updated packages have been patched to correct this issue.
